Sure, you can fabricate your own in-cab winch control for less than $30, but will you?
I wanted an in-cab control for my Warn 8274 for quite some time, but never seemed to get around to it. Also, I had reservations about switches on the dash - what do you do when you need both hands on the wheel or one hand on the wheel and the other on the shifter and/or emergency brake release?
My solution was to take my old winch controller with a frayed cable, cut the cable about 3' from the controller, and connect it to a 4-pin round male trailer plug. I mounted the 4-pin round trailer socket in the front of my Tuffy console along with a mil-spec power on-off switch. The modified controller stays in the console when not in use (or connected and in my lap or stuffed under the seat in between pulls on tough trails). I bought a replacement winch controller and stored it in my "recovery bag" for those times that I want to control the winch from outside my rig.
This won't work for everyone, but I needed a new winch controller anyway.
